A noisy application might be caused by wavy bearing components, local defects in the rings and balls or by dirt particles in the bearing. While basic requirements on a bearing like stiffness, load capacity, speed limit and service life play a critical role in applications, low noise and vibration are becoming even more important.
All of these bearing quality issues can be tested with bearing vibration equipment by SKF.
High tech analysis and measurement such as frequency analysis (FFT) and further advanced analysis pinpoints faults. Spectral masks help to optimize the bearing performance in the particular customer application.
With some experience, the measurement results of these machines can also be used by experts to detect imperfect manufacturing steps, such as missing honing for example. The introduction of a worldwide calibration system permits vibration equipment to be set to operate according to international standards.
